LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED

Malus Domestica

VARIETY DENOMINATION

Alvina

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of apple tree named ‘Alvina’. The new tree resulted from the discovery of a whole tree mutation in a Gala orchard in 2000. The resulting tree was selected when growing in a cultivated area in Drouin, Victoria, Australia.

BRIEF SUMMARY OF THE INVENTION

The ‘Alvina’ variety is distinguished from other apple varieties due to the following unique combination of characteristics: very high level of fruit over color, with solid flush and stripes and maturing earlier than comparator Gala selections.

Asexual reproduction of this new variety was performed by budding and grafting and showed that the foregoing characteristics come true to type.

The following detailed description concerns the original tree, ‘Alvina’. The original tree and progeny have been observed growing in a cultivated area in Drouin, Victoria, Australia. Certain characteristics of this variety, such as growth and color, may change with changing environmental conditions (e.g., light, temperature, moisture, nutrient availability, or other factors). Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color designations are made with reference to The Royal Horticultural Society (R.H.S.) Colour Chart.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a photograph of representative apples from the ‘Alvina’ variety taken in February 2007 in Droulin, Victoria, Australia.

FIG. 2 is a photograph of a cross-sections of representative apples from the ‘Alvina’ variety taken in February 2007 in Droulin, Victoria, Australia.

The colors of an illustration of this type may vary with lighting and other conditions under which conditions and, therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.

DETAILED DESCRIPTION

The following detailed description of the ‘Alvina’ variety is based on observations of 10 trees. The observed progeny are trees which were 5 years of age and growing on M26 rootstock in the orchard in Drouin, Victoria, Australia.
